FASTENING FOR CAR-DOORS.

SPECIFICATION forming part of Letters Patent No. 363,935, dated May 31, 1887.

Application tiled March 14, 1887. Serial No. 230,821. (No model.)

To all whom, it may concern:

Be it known that I, CHARLES G. WREN- sHALL,of St. Paul, in the county of Ramsey and State of Minnesota, have invented certain new and useful Improvements in Fastenings for Car- Doors, of which the following is a specification.

My invention relates to an improvement in the means for fastening and securing the sliding doors ordinarily used in freight-cars; and it consists, generally, in the construction and combination hereinafter described, and particularly pointed out in the claims.

In the drawings which form a part of this specification, Figure 1 is aside elevation of a portion of a car, showing the door with my improved device attached thereto. 'Fig. 2 is a vertical section of the sanne. Figs. 3, 4, and 5 are details.

ln the drawings, 2 represents the car-door, supported at the bottom upon rollers 4, which travel upon the track 6, andat the top held in position by guides 8, which slide upon the bar 10. These parts may all be of the ordinary form of construction.

12 is a bar or bolt, preferably located centrally upon the outer surface ofthe door and arranged to slide vertically in bearings 14, which are attached to the door.

16 is a bar which extends horizontally be'low the door,and may be secured to the body of the car or to the track 6. The upper end of the bolt 12 is preferably recessed to receive the bar 10, and the lower end is U-shaped and eX- tends under and embraces the bar 16. The bars 10 and 16 are preferably provided with notches 17 and 19, cut in their lower edges and of a size to receive the ends of the bolt 12 when brought in line with them. These notches may be placed at any desired position upon the bars, and as many of them as may be found I preferl to construct the b ars with two sets of notches-one set to receive the bolt when the cardoor is open and one set to receive it when the door is closed, as shown in Fig. 1.

18 is a rectangular handle or operating-lever held in bearings 20, which are secured to the cur-door and in which the said handle is free to oscillate in a vertical direction. The poroffset to form the crank 22. This crank is embraced by a strap, 24., which is also provided with ahinge-joint, 26, to compensate for the revolving motion ofthe crank 22. The lower portionvof this hinge is secured to the bolt 12.

It will be seen that by oscillating the handle 18 motion will be imparted by means of the crank 22, through the strap 24, to the bolt 12.

The lowersection of the handle 18 is slotted to receive a tongue or staple, 28, on the bolt 12. This staple is preferably provided with pinholes to receive the pin 30, and this secures the handle in its downward position. A lock crear-seal may be vattached to this-staple and the bolt then 'permanently locked or sealed.

The crank 22 is so formed as to bring the offset above the center when the handle is in a downward position. This allows the weight of the handle 18 to-act to keep the bolt 12 raised.

The operation is as follows: The door being in the position shown in Fig. 1,the bolts 12 are forced into the recesses 17. To open. the door the handle is raised. This causes the bolt 12 to be lowered until it is free from the notches 17. The door is then forced back to any desired point.

Should it .be desired to secure the door open it is carried back until the bolt corresponds with the notches 19, when the handle is brought to its downward position, and this motion carries the bolt upward and into the notches 19, and the door is prevented from sliding until the bolt is released. In closing the door again the same operation is repeated and the lock or car-seal attached to the staple, and the door `is securely fastened.

The weight of the handle holds the bolt in engagement with itsnotches, both when the door is opened and when it is closed. Y

When this device is used, it will be impossible for any one to pry the door open or remove the staple that holds the lock. Another advantage is, that as the fastening and handle are at the center of the door, it is easier to move the door by grasping the handle than it is when the handle is at oneedge of the door, as they are ordinarily placed. The handle 18- serves both as a lever for operating the sliding bolt and as a handle for opening or closing the release the bolt, and open the door without letting go of the handle, or can likewise grasp the handle, close the door, and engage the bolt to fasten the door.

5 I claim as my invention and desire to secure by Letters Patent- 1. rlhe combination, with the cardoor, of the bars 10 and 16, having the notches 17 and 19, the vertically-sliding bolt 12, having its up- Io per` end adapted to engage the notches in the bar 10 and its lower U-shaped end adapted to engage the notches in the bar 16, and means foi` moving said bolt 12, substantially as described.

2. The combination, with the car-door, of the notched bars 10 and 16, the vertically-slid- 15 ing bolt moving in guides upon the door and having its ends adapted to engage the notches in the bars, and the handle 18, having the lcrank bend 22 connected with the sliding bolt,
